Let’s discuss the question: which best describes how air moves during convection. We summarize all relevant answers in section Q&A of website Bmxracingthailand.com in category: Blog technology. See more related questions in the comments below.
What moving air does convection cause?
Convection is the term describing the upward and downward movement of air (or liquids). The underlying cause of these movements is differences in density. Density is the amount of matter in a given amount of space. Dense air sinks, creating downdrafts, while less dense air rises, creating updrafts.
What term is used to describe convection currents in air?
A convection current is a process that involves the movement of energy from one place to another. It is also called convection heat transfer.

What happens during the convection process?
convection, process by which heat is transferred by movement of a heated fluid such as air or water. Natural convection results from the tendency of most fluids to expand when heated—i.e., to become less dense and to rise as a result of the increased buoyancy.
Which of these best describes convection currents?
The best description of a convection current is that e. it is the process in which warm material expands and rises while cool material contracts and…
Which of the following explains convection?
In convection, heat supplied is absorbed by the molecules and the material expands. As this happens, density decreases and heated part of the material begins to move upwards. During the process, heat is transferred by actual motion of the molecules from one place to another.
What is convection explain?
Convection is the transfer of heat by the movement of a fluid (liquid or gas) between areas of different temperature.

How does heat move in convection?
Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated.
What is a convection quizlet?
Define convection. It is the heat transfer in a fluid by the movement of particles in it. Remark A fluid refers to a substane which is able to flow easily. Hence, the substance is generally a liquid or gas.
Which best describes heat transfer due to convection?
Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. Convection above a hot surface occurs because hot air expands, becomes less dense, and rises (see Ideal Gas Law).
Which best describes convection Brainly?
Answer. Explanation: Convection currents move thermal energy from the stove to the pot, and then from the pot to the water. … Convection currents in the water cause warmer, denser water to rise and transfer energy upward.

Which of the following is an example of convection?
Everyday Examples of Convection
radiator – A radiator puts warm air out at the top and draws in cooler air at the bottom. steaming cup of hot tea – The steam you see when drinking a cup of hot tea indicates that heat is being transferred into the air. ice melting – Ice melts because heat moves to the ice from the air.
Which of the following best explains what creates the convection current?
Which of the following best explains what creates this convection current? Salt in the ocean makes it more dense than the land, so its gravity pulls more on the air above it. During the day, the Sun’s energy heats up the land faster, which makes the air above it warmer.
